Inventor: ITO HISASHI
IPC: G01M99/00
Filed: 2001-06-26
Abstract: PROBLEM TO BE SOLVED: To improve evaluation precision of the fatigue damage to a structure. SOLUTION: In a method for evaluating the fatigue damage to a structure, it is conducted such that a crack developed length is measured with a fatigue sensor attached to the structure, an equivalent stress range having an effect on the structure is determined from the number of times of action and the fatigue characteristics indicated in the fatigue sensor, and the fatigue damage which has occurred to date to the structure since the start of the measurement is obtained from both such an equivalent stress range and the fatigue strength of the structure. In the method, further, various kinds of dispersions and errors slipped into the computations of the damage degrees of the structure are determined on quantitative basis.  The probability density or probability distribution of the possible damage degree to the structure is worked out based on the probability/statistical theory considering such unfavorable effects as described above on the computing results. By the establishment of a required probablistic level and by the use of damage degrees corresponding to such a level, the cumulative amounts of the fatigue damage having occurred to date to the structure since its completion are thereby determined and an accumulation amount of the fatigue damage degrees in a future time span is estimated, thereby the remaining service life of the structure is evaluated.
